Electronic surveillance system in communication network and method thereof

Abstract

Provided are an electronic surveillance system and a method thereof. In the electronic surveillance system that performs electronic surveillance on a subscriber in a communication network, the electronic surveillance system includes: one or more communication service providers that provide retained data, which is information generated while the subscriber uses a communication service; a dedicated storage that stores and manages the retained data provided by the communication service providers; and a law enforcement agency that requests the dedicated storage to send electronic surveillance information on a specific subscriber so as to be provided with the surveillance information when the electronic surveillance information on the specific subscriber is required. Accordingly, retained data, which is subscriber electronic surveillance information is integrally managed and stored in a dedicated storage. Thus, a communication service provider can reduce costs when a law enforcement agency requests subscriber electronic surveillance information. Furthermore, the subscriber electronic surveillance information can be efficiently managed.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2006-0124487 filed in the Korean Intellectual Property Office on Dec. 8, 2006, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002](a) Field of the Invention The present invention relates to an electronic surveillance system in a communication network and a method thereof, and more particularly, to a system that provides retained data handover between a communication service provider and a law enforcement agency.[0003](b) Description of the Related Art[0004]Electronic surveillance is a technique by which a communication network provider or a communication network service provider provides subscriber-related information, such as access information on a specific subscriber and telephone call information, when a law enforcement agency legally requests communication electronic surveillance (including audio and ...

AI Technical Summary

Benefits of technology

[0026]The present invention has been made in an effort to provide an electronic surveillance system in a communication network and a method thereof having advantages of providing retained data handover between a communication service provider and a law enforcement agency. An exemplary embodiment of the present invention provides an electronic surveillance system i

Problems solved by technology

Therefore, with the steady development of network technology, the conventional wire tapping device that has been independently operated by the law enforcement agency cannot be efficiently used.

This method has a problem in that a communication service provider has to pay for additional costs since a large amount of information has to be stored, preserved, and managed for a specific time period at the expense of the communication service provider.
